A Snack or the Sacrifice?

Today I would like to elaborate on one aspect of the New Mass -prayers, which accompany so called presentation of the gifts. They are as follows, according to the new translation:

Blessed are you, Lord God of all creation for through your goodness we have received the bread we offer you: fruit of the earth and work of human hands, it will become for us the bread of life.

Blessed are you, Lord God of all creation, for through your goodness we have received the wine we offer you: fruit of the vine and work of human hands it will become our spiritual drink.

Seemingly, they do not appear extraordinary among other prayers in the Missal of Paul VI. However, they source from the jewish prayers. The modernists do not even try to conceal this fact. A good example is provided by the website wiara.pl, where the jewish origins of these texts are explicitly confirmed. Moreover, the prayers used as a model were not random, but these said before a meal were chosen. So, if in the "presentation of gifts" altered jewish prayers are used, may we call the New Mass "fully Catholic" or "the Sacrifice"? The answer is apparent...
